A review on the design of lightweight symmetric block ciphers for cyber physical systems

Abstract

Selection and deployment of security hardware for Cyber Physical Systems (CPS) necessitate a smart choice. Lightweight security algorithms are viable choices for such applications. The study presented, will give an overview of lightweight symmetric block cipher algorithms and provide a summary for algorithm designers of the parameters that influence the design of a cipher algorithm and its impact on security and implementation. Comprehensive review of lightweight, symmetric, Substitution Permutation Network (SPN) type of block ciphers aids the lightweight cryptographic algorithm designer in selection of operations suitable for Cyber Physical Systems. An overall survey on existing lightweight SPN type symmetric block ciphers pertaining to design, security and hardware performance as the three corners that trade-off cipher design is made. The design composition of cipher based on security and hardware cost is the highlight of this paper.
